Title: Carrier pallet for plate fin
Inventor: YAMAGUCHI YOSHIMITSU
IPC: B23Q7/00
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To prevent reduction in positioning accuracy at the position where a tube for heat exchanger is inserted in a group of plate fins forming the core of one heat exchanger. SOLUTION: This carrier pallet 1 for plate fin is separately formed out of a carrier plate 11 and an assembly plate 13 capable of positioning and holding a group of plate fins 2, automatically inserting a tube 3 for a heat exchanger into a group of plate fins 2, and expanding the tube 3 with a group of plate fins 2 mounted. A gap is formed between the outer peripheral wall surface of the assembly plate 13 and the groove wall surface of a fitting groove 22 so that the assembly plate 13 fitted into the fitting groove 22 may be movable horizontally in the roughly square fitting groove 22 formed on the opposite side surface to the carrier surface of the carrier plate 11, thus it is possible to prevent the assembly plate 13 from being affected even if the carrier surface of the carrier plate 11 is worn away or deformed by a handling error or the like.

Title: Method and device for monitoring leakage of gas piping
Inventor: UENO YUICHIRO
IPC: G01M3/24
Filed: 1997-04-07
Abstract: PROBLEM TO BE SOLVED: To detect the fine leakage of a gas piping or the leakage which was undetectably buried in a noise and plot its position. SOLUTION: A pressure wave from a pressure wave generating device 60 is injected into a gas piping to excite the fluctuation in the leakage sound of a gas leakage point Z, and the leakage sound intensified in amplitude and fluctuated in cross correlation is detected by two microphones 11, 12 set in the piping. The cross correlation value is calculated by a cross correlation calculating part 30 from the two A/D converted detection signals. A computer 40 reads the peak value of the correlation values by a delay time calculating part 42, judges gas leakage when it is a threshold or more, and standardizes the leakage position X of gas from the delay time of peak value or the time difference of the microphones 11, 12.

Title: Magnetic recording and reproducing device
Inventor: GOTOU KATSUHIKO
IPC: H04N5/7826
Filed: 1984-05-04
Abstract: PURPOSE:To attain satisfactory reproduction by recording the signal produced from a reference signal given from a reference signal generator on a tape as a control signal when a sound signal accompanied by no video signal is recorded. CONSTITUTION:A reference signal generator 11 can produce a reference signal having extremely high accuracy with use of a quartz, etc. The frequency f0 of a reference output signal 18 is equal to the frequency of a recording control signal 17 produced when a vertical synchronizing signal is supplied through a terminal 16. Therefore the control signal can be recorded on a tape like a video signal even in case only the sound signal accompanied by no video signal is recorded by rotary heads 3 and 4. Then the recorded control signal is reproduced and therefore both heads 3 and 4 can trace accurately over a pattern of sound signals. Thus the reproduction is possible with satisfactory sound quality.

IPC: F04C2/10
Filed: 1992-04-09
Abstract: PURPOSE: To generate brake action for a self-lock hydraulic motor with normal abrasion and damage in the absence of hydraulic pressure by forming a recess of a predetermined shape on an over size toothed surface. CONSTITUTION: Each external tooth 6 of a gear wheel 3 has flanks 8, 9 having recesses 10, 11 arranged thereupon. Each recess 10, 11 has successive curved sections 16, 17, 18 with curving directions different from each other, and a same tangent as the external tooth 6 at the two ends thereof. When hydraulic pressure is applied and the gear wheel 3 rotates about the orbit in a toothed ring 2, an internal tooth 4 of the toothed ring 2 can be sufficiently deeply engaged in the region of the recess 10, 11 without contacting the external tooth 6. Thus, when being pressurized, it is possible to rotate smoothly with slight friction. When hydraulic pressure is interrupted, the pressure between the inlet and outlet of the hydraulic fluid is balanced, the friction of the gear wheel 3 in the toothed ring is relatively large. As a result, brake action is generated.
